EMBROIDERING-MAGHINE.

Application. filed. July 24,

To all whom it may concern:

Be it known that f, GorrWAL'r SIEBER, a

subject of the German Emperor, residing at "ing; is a specification.

' In order to embroider a Whole or uncut piece of fabric on anembroidering machine so @3110 produce a continuous design, the embreidcring must be done in sectlons. To this end, after a portion or onesection of the fabric finished, it is detached from the {fabric frameand Wound upon a certain roller, at the same time unwinding the fabricfrom another roller and bringing a fresh or blank piece of fabric intothe range of the stitching or embroidering implements. At suchmanipulation particular care must be taken that two successive portionsor sections of the design coincide at all points, both on the Verticaland horizontal lines of connection, and that there be no break in thecontinuity of the design. it Was ditfi cult to attain this result,because the threads of the fabric which are very elastic, While thefabric is stretched on the fabric frame, become distended beyond thelimit of their elasticity, so that When the fabric is subsequentlyrelaxed a change of position of the threads of the fabric occurs. Thisdrawback is removed by the present invention, according to which thatend of the finished section of the embroidery with Which the succeedingsection is to be joined, is clamped in an auxiliary frame and stretchedtherein by suitable means Vertically and horimentally Without causingdestruction of the texture of the fabric and maintained in that stateuntil the unfinished section of the embroidery fabric is substituted forthe completed section and is stretched tautly in Specification ofLetters Patent.

The fabric frame a, b, c, d, of an embroidering machine is provided atboth ends With the fabric rollers e, on the roller 2 of which is Woundthe unfinished or blank fabric and on f the finished or embroideredfabric. The part :0 of th fabric Which is to be embroidered and Whichextends over the tainbour frame is in Well known manner fastened to andstretched by longitudinal members Z having hooks Z and suitablysupported on the tambour frame as at Z When that portion or section ofthe fabric has been finished, an auxiliary frame is placed on theembroidered part of the fabric near the end at which it is to connectWith the next portion of the embroidered design and is fixed to thelongitudinal members Z by clamps or other suitable means. The frame iscomposed of vertical adjustable members 9, g and cross members 9, g, themembers 9, 9 being situated near one end of the members 9, 9, so that atthe opposite end an opening g is left. New this frame is so mounted onthe tambour frame that the line 3/g of'the finished section will extendthrough the opening g thereof. Before, however, the completed section ofthe fabric is Wound onto the roller f, z'. 6., While the fabric is stillin a tautly stretched condition on the frame, two rails or bars h, arefixed to the auxiliary frame in such position as to completely inclosethe line of connection y7,/ of the embroidery.

The rails or bars it, e' are provided on their sides facing theembroidery fabric with a covering it comprising a great number of fineWires or prongs over which the embroidery fabric is stretched bysuitable means, the Wires or prongs being made so as not to destroyortear the fabric, While they fully suffice to the fabric rigidly to therails it, 2'. Now that the connection part of the fabric was thus fixedin position, the finished part of the embroidery is unhooked from themembers Z and Wound onto the roller f, leaving the connection partclamped in the auxiliary frame, and is fed onto the roller 7 until theauxiliary frame reaches the dotted line position at the right hand endof the tambour frame. The piece of unfinished fabric unWound from theroller 0 and new extending over the entire length of the tambour frameis then fastened to the longitudinal members Z by hooking it thereto anduniformly and tautly stretched in the tire length of the tambour frame,the removal of the bar it can be efiected without detriment to thegoods, for should it happen that the connection line y3 of the; de--sign after the removal of rail 7t deviates from 1ts vertical position,the error can be easily rectified by correspondingly changing theposition of the-second bar 2', which topossible to have the'difierentsections of the gether with the auxiliaryframe remains on the fabricduring the succeeding period of embroidery operation. In this manner itis design connected at all points with great precision and withoutcausing any tear of the threads'of the fabric.

The wires or prongs 7c of the covering 70 may be covered up by suitablematerial or be themselves made of material that will not rust, so as notto stain the fabric.

What .I claim and desire to secure by. Letp ters Patent is:

1. In an embroidering machine, the combination with thetambour frame, ofa device for fixing the position of the connection line between twosuccessive sections of an embroidery design, and comprising a framecapable of being removably suspendedfrom the'tambour frame and havingdetachable bracing members formed each with a system of gripping meansadapted to grip and hold the fabric in stretched condition.

2. In an embroidering machine, the com bination with the tambour frame,of a device for fixing the position of the connection line between twosuccessive sections of an embroidery design, and'comprising a framecapable of being removably suspended on the tambour frame, anddetachable bracing -members at one end of said frame, each formed on theside facing the fa-bricwith a system of gripping means adapted to gripand holdthe fabric in stretched condition.

3. In an embroidering machine, the combination with the tambour frame,of a device for fixing the position of the connection line between twosuccessive sections of an embroidery design and comprising a framecapable of being suspended from the tambour frame and adapted to be fedalong with the fabric, detachable bracing members at one end of saidframe each formed on the side facing the fabric with gripping or holdingmeans to secure. the fabric in stretched condition.

In testnnony whereof I affix my s1gnature 111. presence of twowitnesses.
